Smartphone charging system has undergone rapid changes over the past few decades , from the use of non - wired to the wired ( LAN ) . In a recent trial , researchers at the Korea Advanced Institute of Science and Technology ( KAIST ) tries to negate the cable strands at all , by developing wireless power transfer technology ( wireless power ) .

The researchers show how systems of Dipole Resonant Coil System ( DCRS ) using two prototype magnetic coil length to power through inductive charging device . The main coil is used to induce a magnetic field , while a handy secondary coil receives power . Once charging is enabled , within 5 meters of a variety of existing electronic devices can still turn .( Read: cara membuat blog yang menarik )

Thanks to the maximum output power of 209 W at 20 kHz , DCRS system has proved the possibility of a new remote power delivery mechanism that has never been attempted on such a long distance . To 100 W of electrical power transfer , the overall system power efficiency is 9.2 % .

T. Chun Rim , Professor of Nuclear & Quantum Engineering at KAIST , assuming similar Wi - Power WiFi network is now available everywhere. With a dimension of 3 meters length x width 10 cm x height 20 cm , DCRS seems to function as a wireless charging station in public places such as restaurants , airports , shopping navel , and so on , without the need of users clustered around the same area .

Wireless technology power cable to charge or download 40 smartphone charger at once . In fact , it can also be used to turn on jumbo TVs .

" With the DCRS , large LED TVs and three 40 W - fans can be activated from a distance of 5 meters , " said Professor Rim , as quoted from Eurekalert Phones Online ( 04/17/2014 ) .

RIM added that this technology can not be marketed commercially , given the relatively high cost of components plus assembly that is not a short term .
